REDCATT 81FIND.8 8 ohm 8-inch Mid-Woofer speaker

The 81FIND is a high efficiency, (96 dB 1watt / 1 meter) 8-inch woofer with linear frequency response characteristics, good power handling capability while generating low harmonic distortion artifacts. The 81FIND uses a lightweight glass-fiber loaded cone assembly along with a high excursion M-roll surround. This combination provides a lightweight, yet strong, piston.

Magnetic Circuit

REDCATT engineers have developed a ferrite based magnetic circuit, capable of delivering the highest level of performance, providing a consistent, high integrity magnetic flux gap, ultra-low distortion characteristic and high-efficiency cooling system. The metal parts are extensively coated to provide the maximum weather protection.
